time limit program, usefull?

hi folks,

don't have any kids myself, but i have talked to a friend a few days ago
who has a software on his windows machine that gives his kids a time
budget they can spend, this way they don't surf the web all day and are
a bit more aware of the time they spend in front of the computer. 

i briefly looked around and couln't find anything similar for linux (of
course i want to convert him and his kids! muhahahha)

i was wondering: do you think something like this is usefull? i am
asking because i have written something very similar a while ago, and
could dig up and adapt the code...

cu  robert
